While this might make sense, I don't think it's a necessary addition.
I think we should wait to see how much this feature is used in
practice and let that be a guide as to how to make improvements.
Defining what "fallback" means is tricky and I think an unnecessary
complication at this level.

This is really intended for situations where a downloadable font
is used, where an author can explicitly select a language system
that he knows exists within the font data.
